Alberto Schiabel f5ff810f2e refactor(cli): define services with Context.Tag and thread argv explicitly (#4359)
This PR:

- builds on top of https://github.com/ComposioHQ/composio/pull/4358
- replaces the eleven `Effect.Service` files (fourteen services) with
`Context.Tag` classes that export a `<Name>Shape` type and an explicit
`static readonly Default` layer built from a `make<Name>` constructor
- removes the three `accessors: true` declarations; nothing in `src/`
used a generated accessor, and the one test that did now yields the
service
- builds test doubles with `Service.of({ ... })` instead of `new
Service({ ... })`, and types helper parameters with the `Shape` types
where the class had been used as a type
- passes the normalized argv from `bin.ts` into `runCli` and through
`cli-main.ts` instead of mutating `process.argv` and reading it back in
five places
- documents the service pattern in `ts/packages/cli/AGENTS.md`

## Context

Effect v4 replaces `Effect.Service` with `Context.Service`, which
generates neither a `.Default` layer nor accessors; with the
explicit-layer shape already on v3, the port turns each service into a
one-line rename. `Command.runWith` in `effect/unstable/cli` takes user
arguments explicitly, so `cli-main.ts` now receives argv rather than
re-reading process state. Second of three preparation PRs.

## Validation

- `pnpm --filter @composio/cli typecheck`, `validate:boundaries`, and
oxlint clean
- `pnpm --filter @composio/cli test`: 127 files, 1319 tests pass, 1

Composio TypeScript workspace

This directory contains the TypeScript half of the Composio SDK monorepo: the core SDK, provider adapters, the CLI, examples, and end-to-end tests. For an overview of Composio itself, start at the root README and docs.composio.dev.

If you just want to use the SDK:

npm install @composio/core
import { Composio } from '@composio/core';

const composio = new Composio({ apiKey: process.env.COMPOSIO_API_KEY });

const session = await composio.create('user_123');
const tools = await session.tools();

See the @composio/core README and the quickstart for the full flow, including provider setup for your agent framework.

Packages

Published packages:

Package Description
@composio/core The Composio SDK. Ships its TypeScript source and SDK docs so installed copies are inspectable by coding agents.
@composio/slim Same API as @composio/core without the packaged source and docs; smaller install.
composio CLI Standalone CLI binary: search, execute, and script tools from your shell.
@composio/* providers Adapters that format Composio tools for agent frameworks (OpenAI, Anthropic, Vercel AI SDK, LangChain, and more). See the provider table.
@composio/experimental Experimental integrations, currently the Pi provider.
@composio/json-schema-to-zod JSON Schema to Zod conversion.

Internal (unpublished) packages: cli-keyring and cli-local-tools support the CLI; ts-builders generates TypeScript source.

Development

Commands run from the repository root. Install the pinned toolchain first:

mise install
pnpm install

Build and verify:

pnpm build:packages   # build all TS packages
pnpm typecheck        # typecheck all TS packages
pnpm lint:packages    # oxlint over ts/packages
pnpm test             # package unit tests plus example validation

Runtime E2E suites (require credentials):

pnpm test:e2e:node
pnpm test:e2e:deno
pnpm test:e2e:cloudflare
pnpm test:e2e:cli

Scaffolding:

pnpm create:provider <name> [--agentic]   # new provider package
pnpm create:example <name>                # new example under ts/examples

Changesets are required for changes to published packages; see the contribution guidelines.
